1 Claim.

' The present invention relates to new and useful improvements in armature winding machines and has for its primary object to provide a device of this character in which the coils of the armature may be quickly and easily wound.

An important object of the present invention is to provide a device of this character embodying means for guiding the wire into the slots of the armature core as the armature is being wound fully hereinafter described and claimed, reference a being had to the accompanying drawings forming part hereof, wherein like reference numerals refer to like parts throughout, and in which:

Figure 1 is a side elevational view,

Figure 2 is a top plan view,

Figure 3 is a fragmentary sectional view taken substantially on a line 3-3 of Figure 1,

Figure 4 is an enlarged and elevational view of the chuck body showing the wire guides or wings attached thereto, and

Figure 5 is a side elevational view thereof with parts broken away and shown in section.

Referring now to the drawings in detail, wherein, for the purpose of illustration, I have disclosed a preferred embodiment of the invention, the numeral 5 designates a drive shaft journaled in bearings 6 supported on a suitable base or stand I on a work bench 8, the rear end of the shaft having a bevel gear 9 secured thereto driven by a similar gear in from a suitable source of power.

To the front end of the shaft 5 is secured a chuck body ll formed with a channel 12 in its front face to receive one side of the core 13 of an armature, the channel l2 of the chuck 'body having a longitudinally extending slot l4 therein for receiving a key 15 adapted to enter one of the slots l6 of the armature core to secure the armature in a fixed. position therein and against rotation or turning movement in the channel.

To each longitudinal side edge of the channel l2 at the front face of the chuck body H is secured a wire guide or wing I! having its ends curved rearwardly, as indicated at 18. The outer side edges of the wings or wire guides are also curved rearwardly, as indicated at l9, and one end of the wings or guides is formed with an inwardly projecting extension with the extensions of the respective wings terminating in spaced relation with respect to each other to form an opening 2| therebetween in alignment with the key IE to provide access thereto for removal of the key from the slot l4 when locking the armature in an adjusted position.

The inner edges of the wings or wire guides IT terminate adjacent a pair of the slots l6, as shown in Figure 3 of the drawing, whereby to guide the wire 22 in the slot of the armature core in the usual manner well known in the art.

As shown more clearly in Figure 1 of the drawing, the curved ends 18 of the wire guides or wings H are spaced from the commutator 23 of the armature whereby the wire may be fed to the slots of the armature core without interference by the commutator and without necessitating a removal of the commutator from the armature.

The opposite side of the armature core I3 is engaged by a tail stock clamp 24 for retaining the armature core in the channel l2, the clamp 24 also being formed with a channel 25 conforming to the curvature of the armature and is secured at one end of a shaft 26 journaled in a pair of intermediate and end bearings for said shaft designated 21, 21, respectively, and supported on a base 28 above the bench 8.

The clamp 24 is yieldably held in position by means of a coil spring 29 having one end bearing against the end bearing 21' and with its other end bearing against a collar 38 secured to the shaft.

It is believed the details of construction, manner of operation and advantages of the device will be readily understood from the foregoing, it being apparent that the armature core I3 is clamped in position between the chuck body II and. the tail stock clamp 24, and upon rotation of the shaft 5 the armature core will be turned so that the wire 22 will be guided in the slots it by the wire guides or wings l1.

In view of the foregoing description taken in conjunction with the accompanying drawings, it is believed that a clear understanding of the construction, operation and advantages of the device will be quite apparent to those skilled in this art. A more detailed description is accordingly deemed unnecessary.

It is to be understood, however, that even though I have herein shown and described a preferred embodiment of my invention that the same is susceptible to certain changes fully comprehended by the spirit of the invention as herein described and the scope of the appended claim.

Having thus described the invention, what I claim is:

An armature winding machine comprising a chuck body shaped to receive one side of an armature core,1a, key removabl y '3Ga1IIi8d.;by the chuck body for engaging the core tosecure thelatter against rotation in the body, means for rotating the chuck body, a releasable rotating clamp engaging an opposite side otthe coret said core including a commutator at one end, and

a pair of wire guides attached to thechuck-bodm at opposite sides of the core, said guides comprising plates having rearwardly curved outer side and end portions adapted to feed the-wire into the slots of the armature between the core and commutator, said plates at oneend having lateral extensions turned toward each other and 4 spaced apart to provide an opening therebetween in alignment with said key for removal of said key therethrough.
